Answer:
67.5 percent (if you're rounding up 68 percent)
Step-by-step explanation:
10,500/15,540 which equals 0.675 turn this into a percent which is 67.5%
 
        
             
        
        
        
The base angles are both equal to (180-70) / 2 =  55 degrees
and 1/2 base = 123 
so we have tan 55 =  a / 123  where a = altitude
a = 123 * tan55 =  175.66

Hello,
Adding the 2 equations,
x+y+x-y=k+k ==>2x=2k==>x=k
if x=k, y=k-k=0
solution is (k,0)
        
                    
             
        
        
        
The triangle G'H'I' is congruent to MNO because they have two angles and the included side equal, therefore, the congruence criteria is ASA.
Answer: ASA
